Other Applications

Eickmeyer & Associates, Inc. has been designing and successfully implementing the CATACARB Process for ammonia and hydrogen plant applications since the early 1960s, with experience in over 80 hydrogen and ammonia applications. In fact, many of the early implementations of the CATACARB Process are still operational and serviced by Eickmeyer & Associates, Inc. to this day.

For hydrocracking and hydrodesulfurization in petroleum refineries, and for the Haber Bosch ammonia synthesis process, hydrogen gas containing low amounts of CO₂ are required. Using the CATACARB Process, hydrogen gas can be brought down to below 2000 ppmv of CO₂. The resulting CO₂ byproduct stream of > 99% purity can then be used for applications like urea production, beverage manufacturing, enhanced oil recovery, and CO₂ sequestration.

The CATACARB Process requires low capital investment and has a relatively high heat efficiency as compared with Amine scrubbing systems. Furthermore, the HPC solution catalyzed by our signature organic catalyst offers > 15% mass transfer efficiency benefits over traditional HPC systems that are catalyzed by DEA. With the added benefits of higher resistance to oxidation, lower vapor losses, and lower dosages, our CATACARB organic catalyst ensures exceptional performance while having improved economics.

Presence of CO₂ in natural gas reduces its heating value, causes increased costs for compression/liquefaction, and causes corrosion of pipelines when water is present. The CATACARB process has proven to be a reliable and effective method for CO₂ removal from natural gas using our CATACARB inorganic catalyst.

Autoclaves with oxygen feed gas consume oxygen in the process of oxidizing refractory ore. To maintain effectiveness, the oxygen content must be kept sufficiently high. CO₂ removal from autoclave effluent gas recovers pure oxygen for recycle to the autoclave, limiting high-pressure oxygen consumption. The CATACARB Process, using our CATACARB inorganic catalyst, has been implemented in autoclave recycle loops to do just that and has been proven effective.

For methanol synthesis from syngas, the ratio of hydrogen to carbon dioxide and carbon monoxide must be controlled for optimization. To achieve an optimal composition of hydrogen and carbon monoxide, CO₂ can be removed from the syngas using the CATACARB Process. In fact, methanol synthesis gas was one of the first CATACARB implementations in 1963.

The decomposition of ammonium nitrate to produce nitrous oxide also yields an undesirable byproduct, CO₂, which must be removed to produce pure N₂. First implemented into an N₂O production plant in 1984, the CATACARB process can selectively absorb CO₂ from an N₂O stream.
